Character augmentations can now also be placed onto 3D objects, and no longer have to be placed directly onto the spatial map, remediating a “GetRemainingDistance” error that would be flagged every frame otherwise

We renamed the ‘apply’ button to ‘done’ in the calibration dialogue to be more precise


We fixed bugs in the video augmentation that would overwrite the currently selected video when cancelling the camera dialogue

We fixed both create and view tutorials, including fixing the way the tutorial activity for the viewing tutorial is downloaded from a resource folder

We decommissioned the IBM Watson assistant service and replaced it with openAI’s chatGPT

We upgraded online error handling to the full Sentry package, improving breadcrumbs and the stack trace, as well as adding session and user info for authenticated users

We implemented a slider for verbosity levels for in-app bug tracking

We reduced StyleCop to documentation checks in the MirageXR assembly, and disabled a large portion of warnings on external projects and packages

The editor 3D grid and the snap-to-grid placement support are now active by default.

We redesigned the user interface of the label editor.

We redesigned the user interface for the audio augmentation editor panel.

We refactored the autosave functionality, which stores data locally immediately, which had shown some erratic behavior, sometimes missing saving changes.


We improved handling of 3D models to prevent them from slipping under the floor level. On rare occasions, as a result of calibration or tracking errors, models may still end up under the floor level, but this can now be fixed using the markerless calibration.

We fixed a bug with re-editing image augmentations, where confirming without changing the image would produce an exception.

The handle for rotating an action glyph (left and right) is now switched on again.

Activity title and description can no longer be edited in view mode.

We removed the zombie ‘home’ button on the aura from the mobile UI.

Values for gaze triggers are now properly saved for Action augmentations.

We refactored the Sketchfab communication, reducing debug log output and phasing out reporting of hard exceptions from expired credentials.

We fixed a few bugs for the label augmentation: Minimizing the edit panel no longer makes the whole menu disappear, re-editing of the step target now recovers the stored value correctly, and pre-selects it in the list; labels of old activities are imported correctly again, and, additionally, label text is now displayed in the list of augmentations, making it easier to identify the right item.


We set up sponsorship support for our GitHub project – please donate large and plenty 🙂

We fixed the xAPI implementation, also modifying the underlying i5 service, which prevented LRS communication from running, also improving the overall error handling (e.g. LRS selection under profile triggered an error).

We fixed the sensor communication framework (VestService.cs and vestconfig.json), which failed to find its config file, and set http://test.mosquitto.org:1883 as default service, which can be used to test communication with sensors from within activities.

We improved the update and clone dialogue messages for the Moodle cloud uploads.

We fixed a bug, where login with the Moodle username (instead of the registered email) would allow logging in, but prevent publishing. Users now need to log in with the registered email address.

Activities that exist only locally (and are not uploaded to the cloud) now no longer try to increase the Moodle hit counter, previously yielding an error.

We added the possibility to configure the calibration marker to the BrandManager.


We implemented a new Exception Manager that captures exceptions globally and logs them live to Sentry.io for improved online error reporting.

We reorganized the folder structure and location of project files to be more logical.

We improved debug logging, now supporting the setting of different levels of verbosity.

We changed the glTF plugin implementation to gltfast, which also resolves issues with animations.

xAPI calls are now suppressed when running in the editor, to avoid spamming the record store, while still maintaining their execution for testing purposes.

To ease in-editor testing, we now assume a random world-origin position during play-mode. This makes it easier to spot problems in restoring positions following calibration.

We introduced one-button dialogues.

We switched the CI pipeline to scheduled builds, to prevent disk space on the container from overflowing quickly in periods of heightened commits.

We added several new wiki pages and updated existing ones (Exception Manager, Experience Manager, Events, Character Model, Compiling MirageXR, File Organisation, UI 2.0).

Release v.2.4.2 11 Oct 2023

We cleaned up code for glyph, image, and audio augmentations.


We fixed a bug where Sketchfab models containing the “/” character would cause the app to crash.
We removed world space UI remnants from mobile builds.
We fixed a bug for the custom 3D models in the Pick and place augmentation.
We fixed a bug with triggers, causing the jump to action step to interpret the wrong step index.


The default unity Debug.Log() is now replaced by a new custom logging system which filters messages based on their importance level. The changes to the UI for setting the desired filter level will be added in a later version. For now, it is possible to change the filter level using Debug.MinimumLogLevel.
Release v.2.3 26 Jul 2023


We rewrote the calibration routines for both edit mode and view mode, adding a floor manager to allow setting the floor plane.
We added gallery upload functionality on mobiles for the step marker feature of task stations and for the image/video augmentations.
We added a player tutorial for mobiles and smart glasses which uses a tutorial activity that is written out internally every time the tutorial is started to ensure the viewer tutorial is not modified by the user.
The marker feature of task stations now shows up with a preview thumbnail button in view mode.
We added auto-saving of the activity title.


We simplified the functionality of the pick and place augmentation, added a trigger for incorrect placement, and improved its manipulation when using a 3D model instead of the default arrow.
We added auto-detection of orientation for images.
